Previous Comments: ------------------------------------------------------------------------ [2005-02-03 13:17:36] mandersm at student dot ethz dot ch Description: ------------ I tried to write a workaround for [no exceptions are allowed to 'raise through' __autoload or a fatal error will occur, http://bugs.php.net/bug.php?id=31816 ] by catching every exception thrown in __autoload. This works fine except for: When multiple E_STRICT errors occur during inclusion and get handled by some error handler which throws an exception instead of displaying it, they can't get caught anymore, causing a fatal error (thrown exception in __autoload). - The E_STRICT errors are caused by the deprecated 'var $var' syntax. - I suspect this bug(?) to apply to other PHP errors that cause a thrown exception during inclusion. I couldn't verify this though because i can't think of another error during inclusion that isn't fatal. - This does not occur when only one E_STRICT error exception gets thrown. - This is not reproducable without __autoload (by just trying to include the file in {main}, catching the exception and seeing if an unhandled one remains) My config line: './configure' '--with-xslt' '--enable-sockets' '--with-apxs2=/usr/local/apache2/bin/apxs' '--enable-fastcgi' '--with-libxml' '--with-openssl' '--enable-ftp' '--with-gd' '--with-pgsql=/usr/local/pgsql' '--with-zlib-dir=/usr/lib/' '--disable-cgi' '--disable-magic-quotes' '--with-jpeg-dir=/usr/lib/' '--with-dom' '--with-dom-xslt' '--with-mysql=/usr/local/mysql-standard-4.0.23-pc-linux-i686' Reproduce code: --------------- File 'test.class.php': <?php class Test { var $deprecated_var1; var $deprecated_var2; } ?> File 'proof.php': <?php function error_handler($errno, $errstr) { throw new Exception($errstr, $errno); } function __autoload($class_name) { try { include('test.class.php'); } catch (Exception $e) { // handle it } } set_error_handler('error_handler'); $test_class = new Test(); ?> Expected result: ---------------- No output at all. __autoload() should run smoothly since any exceptions should get caught before returning, hence preventing a fatal error. Actual result: -------------- Fatal error: Function __autoload(Test) threw an exception of type 'Exception' in /home/smartloader/htdocs/proof.php on line 14 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31827&edit=1
